Vitrinite - Wikipedia
网页Vitrinite is a type of maceral, where "macerals" are organic components of coal analogous to the "minerals" of rocks. Vitrinite has a shiny appearance resembling glass (vitreous). It is derived from the cell-wall material or woody tissue of the plants from which coal was formed.

网页镜质体（英语： vitrinite ）是煤和沉积物中干酪根（英语： kerogen ）的有机成分之一，具有类似于玻璃质的光反射。它来源于植物的细胞壁或木质组织。在化学上，它由聚合物、纤维素和木质素组成 [1] 。镜质躰是煤中最常见的成分。
Vitrinite - an overview | ScienceDirect Topics
网页Vitrinite refers to organic matter derived from terrestrial plants in coals and shales, with low oil generation potential and high methane generation potential. It is commonly used to indicate the thermal maturity of rocks based on its reflectance, which increases with temperature due to structural changes.
Vitrinite Reflectance Analysis | SpringerLink
网页2021年12月22日 · Vitrinite is the dominant component of humic coal and is found as a minor component dispersed into sedimentary rocks, especially mudrocks, the primary source rocks for petroleum. Vitrinite reflectance analysis is the microscopical determination of the reflectance of incident light from vitrinite as calibrated to standards of known reflectance.
镜质组反射率 - 百度百科
网页镜质组反射率（vitrinite reflectance）是指在反射光中的反射光强相对于垂直入射光强的百分比，是煤岩学的研究内容之一。 其中，煤的镜质组反射率是表征煤化度的重要指标。
Vitrinite reflectance, Coal Analysis, Kentucky Geological Survey ...
网页2023年1月5日 · Vitrinite reflectance is the proportion of incident light reflected from a polished vitrinite surface. Vitrinite is a maceral (an organic component) of coal. As vitrinite is heated in the earth during burial, it systematically changes its reflective properties.
Vitrinite Reflectance Service | U.S. Geological Survey - USGS.gov
网页2018年11月16日 · Vitrinite reflectance measures the percentage of incident light that is reflected from the surface of vitrinite as calibrated to a standard of known reflectance. This measurement is often regarded as the gold standard thermal maturity parameter and is used in oil and gas resource assessment and basin analysis studies.
